HOT-WATER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 354,305, dated December14,1886.

Application filed April 14, 1886.

.To all whom, it may concern:

Be it known that I, SAM. F. COLLINS, of Binghamton, in the county ofBroome and State of New York, have invented new and useful Improvementsin Hot-\Vater Apparatus, of which the followingis a full, clear, andexact description.

This invention relates to attachments for boilers or vessels from whichfrequent drafts of hot water have to be taken, and in which it isdesirable to keep the water at a uniform or given temperature, that mayeither be above or below the boiling-point.

The invention is not restricted to use in connection with any particularform of boiler or vessel, nor to any special application of its use,whether for domestic purposes, including the supplying of hot water tobath-tubs, washsinks, laundries, kitchens, and other places where hotwater isused, or otherwise.

In apparatus of this kind it is usual to heat the water, which is fedinto the water heater or boiler as required, by passing a current ofsteam derived from another boiler through the body of water in saidheater-as, for instance, by circulating the steam through a coil ofpipes therein. W'henever'such apparatus is used there is usually muctrouble in keeping the water in the heater a a uniform temperature,owing to the irregular drafts made upon the same, the irregular i fluxof cool or feed water thereto, and the varying temperature or irregularsupply of thesteam used in heating the body of water in the heater, andin some cases it has required almost the constant vigilance of anattendant to regulate the heat of the water by turning the steam on andoft,

otherwise when drawing from the heater either water much too cool, orsteam, instead of water, is discharged from the heater.

My invention consists in a combination, with an apparatus of the abovedescription, of certain means, substantially as hereinafter described,and pointed out in the claims, for antomatically regulating the heat ofthe water in the boiler or vessel from which the drafts of hot water aremade.

Reference being bad to the aceompanying drawings, Figure 1 represents aside elevation,

partly broken. away to show the interior of a hot-water-supply apparatuswith. my invention applied 5 and Fig. 2 is an end elevation of theSerial No. 198,812. (X0 modclzl 1 and O is the usual steam-coil withinthe body of water in said vessel or heater for heating the water in saidvessel.

0 is the pipe for supplying live steam to the coil 0, and D the valve,which should be a counterweighted one of suitable construction, forturning on and shutting off the steam.

E is the usual or any suitable steam-trap for discharging the water ofcondensation from the coil 0, with which it is connected by the pipe F.

Arranged inside of the water-heater A is a closed expansion waterchamber or receptacle, G, of suitable capacity, which may be a pipecoiled or straight or of any other desired form. This receptacle G isconnected by a pipe, 0, with astand-pipe, H, having a suitable valve orcook, d, with a box or case, I, having a rub-.

her or other elastic diaphragm, J, below the level of the top of thefilling-pipe H,and upon orin a cup on which rests a spindle, s. Thiss'pindle carries weights 6, and is connected-as, for instance, by a cordor chain, f, passing over pulleys g-with the valve D, and the connectioncarries a weight or weights, 7:, count balancing the weights 6 over thediaph agm J.

The operation of the invention is as follows: The valve dis opened andwater poured down the stand-pipe H to fill the receptacle G andstand-pipe H till the box or case I is charged With water up to a levelwith the diaphragm J. The valve d is then closed. Thus,whenever thewater in the heater A arrives at its required maximum temperature andthe Water in the receptacle G becomes correspondingly or highly heated,the water in said receptacle G expands so as to relieve the pressure ofthe Weights e upon the diaphragm, and by the motion thus given to theconnection between the diaphragm J and the valve D, aided by thecounter-balance h, said valve D is closed and steam shut off from thecoil in the heater A. On the other hand, as the water cools in theheater and in the expansion water-receptacle G therein, the water in thereceptacle G will contract, the diaphragm J will be relieved ofpressure, and the weights e-over the diaphragm will descend. This willcause the valve D to open again, and so turn on the steam to the heater.In this way the valve D is automatically opened and closed to keep up auniform temperature in the generator A, and after the apparatus has beenonce set or regulated by adding to or taking off Weight from over thediaphragm, according to the degree of temperature required,no furtherattention is necessary.

I claim 1. The combination, with the hot water heater and asteam-heating attachment therefor of a closed liquid containingreceptacle Within the heater, a pipe leading outward ing above the levelof the said diaphragm and provided with a cook or valve, a valvec0ntrolling admission of steam to the'steam-heat- SAM.
